Two angles of a quadrilateral are 79° and 154°. What is the sum of the other two angles?

Answers

Answer 1
Answer:

Answer:

sum of other two angles = 127°

Step-by-step explanation:

the sum of the 4 interior angles in a quadrilateral is 360°

subtract the sum of the two given angles from 360° for sum of other two

sum of other two angles = 360° - (79 + 154)° = 360° - 233° = 127°

The leg of a right triangle is 3 units and the hypotenuse is 4 units. What is the length, in units, of the other leg of the triangle?square root of 5
square root of 7

7

Answers

Answer:

square root of 7

Step-by-step explanation:

Each right angle triangle has 3 sides known as the opposite, adjacent and hypotenuse sides. The relationship between these 3 sides is as defined by pythagoras theorem which states that

a² + b² = c²

where a and b are the lengths of the opposite and adjacent sides (in no particular order) and c is the length of the hypotenuse side.

Given that the leg of a right triangle is 3 units and the hypotenuse is 4 units, it means that

a² + 3² = 4

where a is the length in units, of the other leg of the triangle

a² = 4² - 3

a² = 16 - 9

= 7

a = √7

1)If (x-2) is a factor of x2+ 3ax -2a, then find the value of a

Answers

Answer:

x - 2 => x = 2

x² + 3ax - 2a

=> 2² + 3 × a × 2 - 2 × a

=> 4 + 6a - 2a

=> 4 + 4a

=> 4 ( 1 + a )

★ 1 + a = 0

a = -1

The equation sin (40)= b/20 can be used to determine the length of line segment AC. What is the length of AC? Round to the nearest tenth.

Answers

Provided that the triangle looks like this:

A| \  |   \  |    \  |     \  |      \ b|        \   20  |           \  |              \  |                \  |                 \  |_______40\C      a          B

Then using the the equation to solve for line segment AC (or b on the diagram):

sin(40) = b/20

b = 20 * sin 40
b = segment AC = 12.9 units
